SULKY-PLOW.

SPECIFICATION forming part of Letters Patent No. 232,268, datedSeptember 14, 1880,

Application filed June 17, 1880. (No model.)

To all whom it may concern Be it known that I, THOMAS T. HARRISON, ofAubrey, in the county of Johnson and State of Kansas, have invented anew and useful Improvement in Sulky-Plows, of which the following is aspecification.

Figure 1, Sheet 1, is a side elevation of the improvement. Fig. 2, Sheet1, is a rear clevation. Fig. 3, Sheet 2,is a sectional side elevation.Fig. 4, Sheet 2, is a detail perspective view of the axlearm. Fig. 5,Sheet 2, is a plan view of the locking-hook. Fig.6, Sheet 2, is asectional elevation, showing the halfboxes for connecting theplow-crank, arched bar, and adjusting-lever. Fig. 7, Sheet 2, is asectional elevation, showing the half-boxes for connecting theplow-crank and arched bar.

Similar letters of reference indicate corresponding parts.

The object of this invention is to improve the construction of thesulky-plows for which Letters Patent No. 218,734 were issued to meAugust 19, 1879, in such a manner that they will be simpler inconstruction, more easily controlled, more reliable in operation, andbetter adapted to receive different kinds of plows.

A are the wheels, which revolve upon the axle arms or spindles B. Theinner ends of the spindles B are squared to fit into square holes in thevertical end parts, 0, of the axles D, where they'are secured in placeby. nuts.

Several holes are formed in the vertical ends G of the axles D, toreceive the ends of the spindles B, so that the carriage may be adjusted higher or lower, as the'height of the plow beam may require.

The axles D, at the lower ends of the vertical end parts 0, are bentrearward or forward and then upward, and pass through holes in the endsof the arched bar E and the cross-beam F. The middle part of thecross-beam F rests upon the middle part of the arch or bend of thearched bar E, to which it is secured by staples, eyebolts, or othersuitable means.

When both wheels Aof the carriage are running upon a level, as whenpassing from place to place,the ends of the arched bar E rest uponcollars G, formed upon or attached to the axles D.

The axle D of the furrow-wheel A passes through a hole in the outer endof an arm, H, which is secured in place adjustably upon the said axle Dby a set-screw, I. The inner end of the arm H is widened and flattenedto serve as a plate to receive the end of the crankscrew J, which passesthrough a nut, K, formed in or attached to the crossbeam F at a littledistance from the axle D, so that by turning the crank-screw J theframe-work of the carriage can be leveled at whatever depth the furrow-wheel may be runnin The axles D may be adjusted with the spindles Bin front or in the rear, or one in front and the other in the rear, asmay be desired. The upper ends of the axles l) are squared to fit intosquare holes in the forward ends of the short bars L, the rear ends ofwhich are bolted to the ends of the cross-bar M, the fasteningbolt atthe landside end of the crossbar M passing through a slot in the end ofthe said cross-bar M, so that the wheel A can be adjusted to run true toprevent the spindle B from being worn.

N is the tongue, which is secured to the crossbeam F by a staple, O, orother suitable means. The rear end of the tongue N projects in the rearof the cross-beam F, and passes through a loop or stirrup, P, the endsof which are bolted to the cross-bar M, the fastening-bolts passingthrough slots in the said cross-bar M, so that the tongue N can beadjusted to cause the plow to take or leave land, as required.

The tongueN is heldin position and strengthened against side strain bythe braces Q, the forward ends of which are bolted to the opposit-esides of the tongue N. The rear ends of the braces Q are secured to thehorizontal end parts of the arched bar E.

To the middle parts of the braces Q, is secured a plate, 1%, whichserves asa foot-rest for the driver, and which is slotted to receive thebelt that fastens to it the upper end of the loop S. The loop S receivesthe forward part of the beam T of the plow U and holds the said beamfrom lateral movement. The side bars of the loop S have a number ofholes formed through them to receive a pin or bolt, V, to prevent theforward end of the plowbeam from rising.

The pin or bolt V is provided with a tubular washer or hollow roller, tocome in contact with the beam T and prevent the said beam from beingworn.

To the pin or bolt V is pivoted the forked end of the lever W, the upperend of which projects into such a position that it can be readilyreached and operated by the driver from his seat. The lever V is bent,as shown in Fig. 2, into such a shape that when its upper end is drawnto the rearward its lower part will force the forward part of theplowbeam T downward to cause the plow to enter the ground. The lever 'Wmay be reversed so as to pass up in front of the foot-rest B, so that iteanbe operated by the driver with his foot. The lever is especiallyuseful in plowing hard and trashy land.

To the opposite sides of the rear part of the plow-beam T are attachedthe lower ends of .two bars, 90, by bolts, clamps, or other suitablemeans. In the rear ends of the bars :10 are formed holes to receivetheiniddle part of the crank-bar Y, where they are secured in place by acollar, Z, placed between them upon the crank-bar Y, and secured inplace by a setscrew, to, so that the plow may be adjusted to cut wideror narrower furrows by adjusting the collar Z upon the crank-bar Y.

In the ends of the crank-bar Y are formed half-bearings b, to receivethe horizontal end parts of the arched bar E, where they are secured inplace by the half-bearings c d, which are bolted to the arms of the saidcrank-bar Y. The half-bearing (Z is formed upon the rearward-projectinglower end of the bent lever e, the upper part of which passes up at thefront of the cross-beam F into such a position that it may beconveniently reached and operated by the plowman from his seat to raisethe plow from the ground when desired.

To the cross-beam F is pivoted a hook,f, to engage with the lever e andlock the said lever in place when holding the plow raised from theground. The hookfis so formed as to serve also as a stop to limit theplay of the lever 0 when the plow is at work. The hook fis extended inthe rear of its pivot, and the extended rear part, g, is bent upwardinto crank form, so that the said crank-hook can be convenienty operatedto release the lever eby the plowman from his seat.

The forward movement of the hook f is limited by a stoppin, h, attachedto the crossbeam F for the rear part, g, to strike against, and againstwhich the said crank-hook f g is held by a coiled spring, 1', attachedto it and to the said cross-beam F.

To the side of the rear part of the tongue N is pivoted a lever, j, thelower part of which is bent to form a shoulder or hook, and its lowerend is inclined, as shown in Figs. 1 and 3, so as to hook upon thecrank-barY and support the plow when raised from the ground and relievethe lever c from the strain.

The wheelsA can be changed from the front to the rear and from the rearto the front of the axles D by detaching the spindles B and the bars L,turning the axles G through a half-revolution, and again attaching thespindles B and bars L.

The machine is adjusted for a left-hand plow by detaching and reversingthe crankbar Y, the lever c, the tongue N, and the braces Q.

The lower edge of the landside or bar of the plow U is horizontal fromthe point to or near the place where the end of the beam T connects withthe said landside, and the said edge from this place to the rear end orheel of the landside is inclined upward, as shown in Figs. 1 and 3. Thisconstruction allows the plow to rock slightly as it is drawn forward, sothatit will pass through the soil more easily.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The spindles B, axles D, having vertical end posts,0, the arched bar E, having end holes, the plate H, crank-screw J, andcrossbeam F, combined, as and for the purpose described.

2. The braces Q, plate 1%, loop S, pin V, bent lever WV, and plow-beamT, combined to adj ustably support the front end ofplow-beam, as shownand described.
